Reviewed by Kshitija Bhandaru
See our latest analysis for Idorsia.
Idorsia’s momentum this year has been remarkable, with its share price up 290% year-to-date and a 177% total shareholder return over the past twelve months, even as volatility picked up in recent weeks. Recent sharp swings suggest that investor confidence is rising on growth prospects; however, longer-term returns remain deeply negative for those holding since before the rally.

The surge in Idorsia’s stock raises a key question for investors: is there still value to be unlocked here, or has the recent rally already incorporated all of the company’s expected future growth?
Most Popular Narrative: 4.5% Undervalued
According to the most widely followed narrative, Idorsia’s fair value has now climbed just above its last close price. After a period of significant optimism and upgraded expectations, this analysis marks a measured shift in outlook compared to previous forecasts.
Optimism regarding the accelerated advancement and eventual commercialization of a broad pipeline (including Fabry disease, chemokine antagonists, and the C. diff vaccine) may be inflating valuation through expectations of long-term multi-asset revenue streams. However, increased cost controls and funding needs persist until 2027 profitability.
Curious about the blockbuster product launches and strategic assumptions fueling this price target? Behind the headline value, there is a tug-of-war between future market expansion and margin breakthroughs. Unlock the narrative to see which big expectations and bold pipeline moves tip the scales.
Result: Fair Value of $4.00 (UNDERVALUED)
Have a read of the narrative in full and understand what's behind the forecasts.
However, strong commercial momentum for QUVIVIQ or major regulatory wins, such as U.S. descheduling, could quickly change expectations and drive upside for Idorsia’s outlook.

Another View: What Multiples Reveal
Looking through a different lens, Idorsia trades at a sales ratio of 3.8x, which is well below both its peer average of 6.5x and the broader European Biotechs sector at 9.3x. However, it still sits above its own fair ratio of 2.8x, highlighting both value relative to rivals and some downside risk if expectations cool. Do investors believe the rally is sustainable, or could sentiment shift if the story changes?
